No injuries were reported, according to the El Centro newspaper. But worldwide use of that model of turbine has been suspended while the mishap is investigated by its manufacturer, Siemens. ...In April, a blade broke from a similar Siemens turbine at an Iowa wind energy facility, the Imperial Valley Press reported.
NAW has learned that a blade belonging to a Siemens SWT-2.3-108 wind turbine came crashing to the ground at the 265 MW Ocotillo Wind Farm in the early morning hours of May 16. No one was injured. A spokesperson from Pattern Energy, which owns and operates Ocotillo, corroborated the incident.
News report of the 173-foot long blade that crashed to the ground and shattered into pieces at the Ocotillo wind facility raises concerns about wind turbines built close to people and sensitive resources. Duration: 3 minutes 29 seconds
A massive blade from one of the 112 wind turbines recently installed was found near a tower base Thursday, after plummeting onto the ground overnight, triggering safety concerns among officials and some residents. ...the project is now shut down.
Siemens does not yet know the root cause of this incident and is working to determine if and how this is related to a recent similar incident in Iowa. Today, Siemens is taking the step of curtailing all turbines with the B53 blade type globally. These turbines will remain curtailed until it can be determined they are not at risk of a similar malfunction. The Iowa incident took place in April at MidAmerican Holdings' 200-megawatt Eclipse wind farm.
A Siemens spokeswoman explained that "when a turbine is curtailed, it means the load on the blade is significantly reduced compared to normal operation." The company said there were about 700 such turbines deployed around the world, with most - around 600 - in the United States, and all those turbines were being examined.
The 315-megawatt Ocotillo Express Wind project in Imperial County is shut down today after a 10-ton blade came loose from one of the project's 112 wind turbines, landing about 100 yards away on a public road.
This wholly avoidable public health and safety hazard occurred just one day after San Diego County Board of Supervisors approved the revised Wind Energy Ordinance & Boulevard Community Plan to remove community protections to allow 500 foot tall industrial wind turbines on private land in previously protected areas near homes, recreation areas, and sensitive wildlife.
At least three wind turbines have been lost to a wildfire that has been burning since late last week in the Jawbone Canyon Recreation Area near Tehachapi, and additional turbines might be threatened. The turbines belonged to NextEra Energy Resources.
Asked directly whether the generator that caused the fire was an actual wind turbine, Captain Ewing confirmed, "Yes ma'am." He also confirmed that ground had been cleared around the base of each turbine, the blaze swiftly spread to become a wildland fire despite those precautions. Captain Ewing did not know the precise cause of the turbine malfunction.
A large wind turbine burst into flame late Friday night in the mountains above Mojave, causing a small grassfire. The fire took place near the intersection of Oak Creek and Tehachapi Willow Springs roads.
By 9:33 p.m., a caller advised the California Highway Patrol authorities that “the ridge is now on fire” near Haugen-Lehmann Way and eastbound Interstate 10. ...Eight homes were evacuated, Gaines said.
The CHP closes roads near runaway wind turbines for the safety of motorists. "The runaway wind turbine, when it deteriorates or explodes, can send scrap metal and steel up to a mile away," said CHP Officer Ed Smith.
William St. Clair, a General Engineering contractor in California, identified a structural failure on a set of welds in ReDriven's 18 meter tower. The tear was expanding, and the tower section above the tear was off center and shifted.
How safe would giant wind turbines, power stations, high voltage lines, and a dump proposed for East County be during a powerful earthquake? Consumer advocates and area residents are raising those questions-and the answers in some cases are unsettling.
Workers are inspecting and repairing 75 wind turbine blades at a wind farm some 60 miles east of San Diego after a storm a month ago caused catastrophic damage to some of them. ..."The turbines were actually stopped," he said. "There were extremely high winds on the site - that contributed to the blade cracking."
A turbine fire at a wind facility approved by Riverside County in California spewed toxic fumes into the homes of nearby residents. The residents describe their experience with the fire. The County supervisors were dismissive of the issue. Duration: 7 minutes 35 seconds
The windturbine that started spinning wildly on May 3 disintegrated two or three days later, according to the California Highway Patrol. All that is left now is a turbine-less twisted tower. The CHP closed Highway 58 for hours after it was notified that the turbine was spinning out of control on Sunday. The closure snarled traffic in the area.
A faulty windmill near Tehachapi shuts down all lanes of Highway 58 between highways 202 and 14; and CHP Officers say it could be days before the roadway re-opens. Mojave CHP got the call about the out-of-control windmill located in the Tehachapi Wind Farm a little after 1:20 Sunday afternoon.
A runaway windmill in Tehachapi closed Highway 58 -- a major east-west freeway connecting California's southern Central Valley to Las Vegas, Nevada and Arizona -- for most of the day Sunday. As of 6:45 p.m., the highway remained closed between Tehachapi and Mojave. Officials had no estimate as to when it might reopen
